Title
(DE) VERFAHREN ZUR HERSTELLUNG EINER ZAHNBÜRSTE AUS KUNSTSTOFF
(EN) METHOD FOR PRODUCING A PLASTIC TOOTHBRUSH
(FR) PROCEDE POUR LA FABRICATION D'UNE BROSSE A DENTS EN PLASTIQUE
Abstract
(DE)
Zur Herstellung einer Zahnbürste aus Kunststoff, insbesondere mit einem Wechselkopf, werden die Halteenden (6) von Borsten (3) durch Lochungen (5) einer Halteplatte (4) oder eines Zahnbürstenkörpers (2) so hindurchgesteckt, dass sie darüber etwas überstehen. Diese Halteenden (6) der Borsten (3) werden miteinander und/oder mit der Halteplatte (4) oder dem Bürstenkörper (2) verschmolzen. Dabei kann vor oder nach dem Verschmelzen wenigstens bereichsweise, zweckmässigerweise jedoch ganzflächig, auf die Halteenden (6) der Borsten (3) oligodynamisches Material (9) insbesondere in flüssiger Form aufgetragen werden, welches entweder beim Verschmelzen in die Schmelze eingearbeitet oder beim Auftragen nach dem Verschmelzen durch Diffusion oder Kapillarwirkung in den Kunststoff der Borsten (3) eindringt. Bei der Benutzung der Zahnbürste und durch die dadurch bewirkte Anfeuchtung wird das oligodynamische Material über die gesamte Borstenlänge verteilt und kann bis zu seiner vollständigen Auswaschung während der Benutzungsdauer eine antibakterielle und keimtötende Wirkung ausüben.
(EN)
To produce a plastic toothbrush, especially a toothbrush comprising an exchangeable brush head, the retaining ends (6) of bristles (3) are pushed through holes (5) in a retaining plate (4) or a toothbrush body (2) in such a way that they protrude slightly. Said retaining ends (6) of the bristles (3) are joined to each other and/or to the retaining plate (4) or the brush body (2) by fusion. In this way, before or after fusion an oligodynamic material (9), especially in liquid form, can be applied at least in partial areas but preferably across the entire surface, on the retaining ends (6) of the bristles (3). Said material is incorporated into the melted mass during fusion or, if it is applied after fusion, penetrates the plastic material of the bristles (3) by diffusion or capillary action. During use of the toothbrush and as a result of the wetting caused thereby, the oligodynamic material is distributed along the full length of the bristles and can have an antibacterial and germicidal action during the duration of use, until it is fully rinsed out.
(FR)
Pour la fabrication d'une brosse à dent en plastique, notamment avec une tête de rechange, les extrémités de retenue (6) des poils (3) sont enfoncées à travers des trous (5) d'une plaque de retenue (4) ou d'un corps de brosse à dents (2) de sorte qu'ils soient un peu saillants. Ces extrémités de retenue (6) des poils (3) s'unissent en fondant et/ou s'unissent avec la plaque de retenue (4) ou avec le corps de brosse (2) en fondant. Il est alors possible d'appliquer avant ou après la fusion, au moins par zones, mais avantageusement sur toute la surface, sur les extrémités de retenue (6) des poils (3) un matériau oligodynamique (9), notamment sous forme liquide, lequel est incorporé dans la matière fondue au cours de la fusion ou bien pénètre dans la matière plastique des poils (3) par diffusion ou capillarité lors de l'application après la fusion. Lors de l'utilisation de la brosse à dents et grâce à l'humidification ainsi provoquée, le matériau oligodynamique est réparti sur toute la longueur des poils et peut exercer, jusqu'à son élimination complète par lavage, une action antibactérienne et germicide pendant la durée d'utilisation.
